南非关联船认定及其应对措施

关联船的认定方式有两种:直接证明式和间接证明式.对于直接证明式的举证,我们要向法院说明我国国有企业的独立法人地位,中国政府对国有企业只有行政管理,不存在商业意义上的控制.对于间接证明式的举证,要淡化索赔人所列举的确实存在的关联因素,驳斥其列举的不存在的关联因素.     

Metrological framework for selecting morphological characters to identify species and estimate developmental maturity of forensically significant insect specimens

Accurate age estimates of immature necrophagous insects associated with a human or animal body can provide evidence of how long the body has been dead. These estimates are based on species-specific details of the insects’ aging processes, and therefore require accurate species identification and developmental stage estimation. Many professionals who produce or use identified organisms as forensic evidence have little training in taxonomy or metrology, and appreciate the availability of formalized principles and standards for biological identification. Taxonomic identifications are usually most readily and economically made using categorical and qualitative morphological characters, but it may be necessary to use less convenient and potentially more ambiguous characters that are continuous and quantitative if two candidate species are closely related, or if identifying developmental stages within a species. Characters should be selected by criteria such as taxonomic specificity and metrological repeatability and relative error. We propose such a hierarchical framework, critique various measurements of immature insects, and suggest some standard approaches to determine the reliability of organismal identifications and measurements in estimating postmortem intervals. Relevant criteria for good characters include high repeatability (including low scope for ambiguity or parallax effects), pronounced discreteness, and small relative error in measurements. These same principles apply to individuation of unique objects in general.

Key points

• Metrological rigour can increase in forensic entomology by selecting measurements based on their metrological qualities.
• Selection of high-quality features for morphological identification of organisms should consider these criteria: (1) pronounced discreteness of features (minimising group overlap or maximizing interval); (2) high repeatability of assessment (such as symmetrical width rather than asymmetrical length); (3) small relative error in measurement (selecting the physically largest continuous rigid feature for measurement).
• These metrological principles also apply to individuation of unique objects in general.

     

论家事案件之执行

家事案件执行具有不同于一般民商事案件执行的显著特点,这类案件的执行,并不仅仅是简单地强制实现判决书上确定的权利,还需要顾及相关当事人的情感和将来良好关系的维持.解决这类案件执行难的问题,必须首先完善我国的现行立法,对家事案件执行设专章加以规定,以便执行人员树立新的执行理念,真正实现家事案件的执行目标.     

刑事案件立案统计不实问题探析

刑事案件立案统计不实是当前影响科学判断社会治安形势的重要因素之一,并影响了制定打击刑事犯罪的决策,因此,在当前和今后一个时期仍要把纠正刑事案件立案不实问题作为一项重点工作来抓,清理和纠正这一制约公安工作发展的瓶颈问题,推动公安工作的良性发展。     

判例在中国传统法中的功能

中国传统法中的判例是指经过特殊程序认定,具有普遍拘束力的司法判决。春秋战国以前,中国的法律以判例为主要存在形式。春秋战国以后,形成了以法典为主,判例为辅,多种形式并存的法律体系并长期保持。法典化时代的判例立足于法典,发挥了对法典在立法范围扩展、立法技术补充、规则效力强化等方面的功能。在判例创制规則和复现规則的关系上,中国古代始终坚持复现为主的原則,在维护法律形式內部稳定结构的同时,维护规则供应的相对稳定。     

案例指导制度的理论基础

实行案例指导制度是要以制定法为主、案例指导为辅,在不影响制定法作为主要法律渊源的前提下,借鉴判例法的一些具体做法。案例指导制度蕴涵着以下法律价值:节约司法资源,提高司法效率;保障法制统一,实现司法公正;发挥司法功能,积极解决纠纷;提高司法能力,遏制司法腐败。实行案例指导制度,是我国法制实践提出的迫切需要,是一种能够体现中国特色、并顺应世界两大法系逐渐融合发展大趋势的制度变革举措。     

Distribution of the Minutiae in Hypothenar Palm Prints in Slovak Adults: Indications for Personal Identification

Minutiae are small distinguishing features found along every ridge flow, which make each friction ridge print unique. The most common friction ridge prints found at the crime scene are fingerprints; therefore, the most of the minutiae studies are focused exactly on this kind of prints. The authors believe that further examination and enlargement of the palm print database could result in better use of the palm prints for personal identification. We analyzed a total of 160 palm prints from 40 females and 40 males aged between 18 and 70 years from Slovakia. For the evaluation of the minutiae, the area of the hypothenar had to be marked out. The classification of the minutiae used for this study was based on a modified version of the classification system using the total of 13 types of minutiae. The frequency of every minutiae type was calculated and, using the chi-square test with Yates's correction, bilateral and sex differences were assessed. The relationship between the different types of minutiae was examined with Pearson's correlation test. During the initial phases of the identification process, the focus should be on the least common types of minutiae (Y or M and return), which were found not to correlate; thus, their mutual occurrence is random (e.g., overlap—Y or M, crossbar—return, or Y or M—dock). The results of the present study show which specific minutiae types are the most suitable for personal identification. These findings may be beneficial in more effective outcome of the identification process.     

DNA Recovery From Tape-Lifting Kits: Methodology and Practice

In the case of suspicious deaths, the technique of 1:1 taping is often used in Belgium. It consists of affixing a large number of adhesive tapes to the body of the victim. It is conventionally aimed at obtaining microtraces (e.g., fibers, hair) and is usually not used for DNA analysis. However, in some cases, DNA analysis of certain areas of interest identified on the 1:1 taping material can offer a last resort solution. The four-step method that is described in this article involves the selection of areas of interest on the body (Step 1), the selection of the corresponding tapes (Step 2), the decontamination of the tapes (Step 3), the selection of areas of interest on the tapes, for DNA sampling (Step 4). The method is illustrated by its successful application in four murder cases. In each case, DNA profiles of good quality could be identified, including profiles of persons different from the victim.
